Welcome Game.
You just write a small illustrated article in Dogfight News and you will be issued a press card. Preferably it would be an article dealing with an actual game situation or something else of general interest to the players.
You may start an extra Dogfight account and sign up with a different identity.
As your in-game name you choose one of the "PHOTO/PHOTOGRAPHER/PHOTOPLANE" names on the list in page 1 (I believe) of this thread. If your preferred name is already in use, you just add a number to it: PHOTOGRAPHER2, PHOTOGRAPHER3 etc...
This system makes it official, and ensures that your identity as Gamekeeper is open and known to all who are interested, even when you fly as PHOTOGRAPHER2.
When squadron games are implemented, there will be a PRESS squad, which will then have the word PRESS above their rank symbols. All members of the PRESS squad will be low rank, and they will all fly cheap planes, but since they never carry bombs they will be able to fly fast enough to keep up with the action.
Central in this photo you see me in my photoplane as I would appear to my team mates when the PRESS squad is activated. Until then there will only be the name "PHOTOGRAPHER" to identify me. I would of course be red to those on the opposite team, but when I say that I'm "non-fighting" and "unarmed", nearly everyone will leave me alone.
